If the valve is not installed immediately after delivery,
it must be put into proper storage.
It should be stored in a dry, vibration-free and well-
ventilated room at as constant a temperature as
possible.
Elastomers are to be protected against UV light.
In general, a storage period of 10 years should not be
exceeded.

disc completely closed or with an opening angle
greater than 15°.

unit is to be 10-15° open.
